Inventor: SCHANIN JONATHAN
IPC: F16G5/12
Filed: 1990-05-18
Granted: 1994-05-31
Abstract: The endless drive belt is produced by winding a pre-formed load-carrying member (6) comprising a cord (8) embedded in a solid but softenable elastic material (10) along and around a surface of  an endless  compression member  belt  (2)  also comprising a solid but softenable elastic material,  thereby forming a layer (4) comprising a plurality of turns, and by simultaneously causing said turns to become intimately bonded to said surface. Said bonding is achieved by applying mutual pressure between said turns and said surface during winding and by selectively softening the surface layers of both said load-carrying member and said endless compression member belt which are to come into contact with each other, just prior to coming into contact with each other. The material of said surface  layers  is  allowed to  fuse.  Said turns  of  said load-carrying member  are further  allowed to be partially impressed in said surface of said endless compression member belt. Softening may be carried out by the application of heat and/or the application of an adhesive. A device for carrying out the above method is also disclosed.  With the device disclosed endless drive belts may be easily produced in-house at the time they are required at any size and at minimal costs and capital outlay.

Title: A delay line providing an adjustable delay
Inventor: MOLIN STUART B
IPC: H03H11/26
Filed: 1991-04-10
Granted: 2000-06-27
Abstract: First and second complementary input voltages control current flow through first and second switches (e.g. semiconductor devices) each respectively connected in first and second control circuits with a first constant current source. When the input voltages change, current starts to increase through one control circuit to produce increases in the voltage drop across an impedance (e.g. resistor) in such circuit. When a particular voltage difference is produced between the impedance voltage and an adjustable biasing voltage, a third switch (e.g.  semiconductor device) closes to produce a first resultant voltage. The resultant delay in the third switch closure is dependent upon the adjustable magnitude of the biasing voltage. As the voltage increases across the impedance in the one control circuit, the voltage decreases across an impedance in the other control circuit, causing a second resultant voltage to be produced at a fourth switch (e.g. semiconductor device). The resultant voltages are respectively introduced to fifth and sixth switches (e.g. semiconductor devices) each connected in a circuit with an individual one of second and third constant current sources. When the resultant voltages change, the particular one of the fifth and sixth switches receiving an increase in current passes a portion of this current through the associated current source and another portion of this current through a coupling member and the other current source. This delays the state of non-conductivity of the switch connected to the other current source. Output voltages further delayed from the input voltages are accordingly obtained from the fifth and sixth switches.

Granted: 1994-12-27
Abstract: ABSTRACT         A compensated amplitude comparison monopulse receiver (10) having an angular measurement capability substantially unaffected by mismatches in channel transient response and target range tracking inaccuracy is disclosed herein.  The inventive monopulse receiver (10)  includes a first receiver channel  (24)  for impressing a first output voltage S1 on a first output port (28) thereof in response to excitation by a sum signal.  A second receiver channel (26)   impresses a second output voltage S2 on a second output port (30) thereof in response to excitation by the sum and a difference signal.  In a calibration mode, a calibration source (22) provides a series of calibration pulses to the first and second channels (24, 26) which induces first and second calibration voltages to appear on the first and second output ports (28, 30) thereof.  Sampling gates (32, 34) sample the first and second calibration voltages subsequent to application of each calibration pulse to the first and second receiver channels (24, 26). In a tracking mode the sample gates (32,  34)  are operative to sample the first and second output voltages i present on the first and second output ports (28, 30). The inventive receiver 10 further includes circuitry (48, 50) for calculating the angular location of the first object from the sampled first and second output voltages. A compensation network (36) then adjusts the calculated angular location on the basis of the sampled calibration voltages.

Granted: 2002-08-27
Abstract: A Foam-Formed nonlaminated stratified paper tissue and method of making the same includes a first zone of foam-formed paper tissue formed from a furnish which is relatively rich in hardwood fiber. A second zone of foam-formed paper tissue is formed from a furnish which is relatively rich in softwood fiber. The second zone is formed unitary and entangled with the first zone to form a nonlaminated stratified paper tissue. A high softness integument is defined adjacent to an outer surface of the first zone and a substratum is defined adjacent to a surface of the second zone spaced away from the integument. The integument on the outer surface of the first zone includes an enriched region wherein the hardwood fiber content is greater than that obtainable in the corresponding region of a tissue obtained from furnishes having the same compositions under the same conditions but employing water-forming instead of foam-forming. The substratum on the surface of the second zone includes a region enriched in softwood fiber. The enriched region of substantially pure hardwood fiber provides an extremely soft and smooth surface as detected by human somatic sensibility.
